Which term refers to the measures taken by a central bank to regulate financial factors like the money supply and interest rates?

Explanation

Option A refers to fiscal policy, which involves government revenue and expenditure decisions. Option B is a broad term that encompasses various economic strategies. Option C, although close, is a misspelling of 'monetary policy.' Since none of the listed options correctly identify the central bank's activities, the correct choice is D, indicating none of the options are correct.
